3. A steam power plant operating with a Rankine cycle has a boiler pressure of 50 bar and a condenser pressure of 0.5 bar. At the steam boiler exit, the steam is superheated to 350C, whereas the feed water is sub-cooled by 10C at the condenser exit. Considering a mass flow rate of steam of 5 kg/s and an isentropic turbine efficiency of 0.84, determine the thermal efficiency and specific steam consumption of the cycle. 4.36 kg/kW-hr] [Ans: 0.303;
